Who can offer the most efficient (i.e. fastest) code to accomplish the following?

I need to search 3,000 ascii text files spread among approximately 20 sub-dirs. The files might contain 200-300 lines, bu I only need to search the first 7 lines of each file for a short keyword that the user will enter into a textbox. I report all matches into a listbox.

My current method opens the file for an ascii read, then "for x= 1 to 7" and use the ATC() function to look for a match on each read line. It works, but it's kinda slow, just becuase there are so many files.

I will post my code when I get to work on Monday, and you can critique it.

Thanks.
